What is photosynthesis?
Leaves of most plants can produce nutrients under sunlight. This process is called photosynthesis.The leaves absorb energy from sunlight, carbon dioxide from the air and water from the soil. Leaves also contain chlorophyll (a green pigment). Nutrients for plant growth and oxygen are released.
Why is the air fresher in places with lots of times during the daytime?
Plants with green leaves perform photosynthesis during the day. The level of carbon dioxide is lower and the oxygen level is higher.
What are pistils?w
Pistils recieve pollen, consists of an ovary and a style
What are stamens?

What are sepals?
Sepals protect the flower bud
What are petals?
